We need this one ASAP.

It doesn't look like Mozilla is going to add this feature, so you can try this instead:

How is this not a thing on 2026? The grey is very annoying on Amoled devices.

Hey folks! I’m happy to share a link where you can get a sneak peek at the new feature our design system team put together for OLED. We’re sure you’re going to really enjoy it. It's coming really soon!

Exciting news...

This is being worked on—check out @3duardo's recent comment in the thread for more info, including a sneak peek 👀

Stay tuned for more updates!

Very happy to learn of this, @3duardo ! Edge holdout here keen to try move over to Firefox completely. The searing white page elements when browsing sites on my mobile OLED devices gives me eyestrain 😞 Bonkers that it took this long and glad that resources are finally being invested into this important QOL feature.

Will the new OLED design system eventually roll out to desktop as well?

Big thanks to @Kerim for taking the time to work on their own implementation of a dark theme for the community. Speaks volumes about your atttitude towards making the mobile experience better for everyone.

I personally prefer to wait for an officially supported and more secure implementation before making the switch 🙂

looks good, can't wait!

I really hope this gets implemented soon! A pure black theme for oled screens would be great and should have been introduced long ago. Just think about the battery we can save, our eyes will be happy and the environment too from less power spent lighting up a grey ui. Custom themes in general has been missed for long now on firefox android. Bring us back the customizability we were used to and love!
